No Reason at All
Dogs bark. That’s the one thing about them we don’t like and we can’t change. That’s just a part of who they are. As simple as that. We can’t control when they bark and why they bark, they just do. Of course, we’d prefer it if they didn’t bark at night, but that’s just out of our control.

They might bark because they hear something outside, or see something outside, they might bark because they’re having a bad dream, and they might bark in the middle of the night for no reason at all. They don’t always bark in the middle of the night, but when they do, often it’s for no reason.
